Please pardon my ignorance but are you people talking about phones which are not android phones that use SIP accounts?
The reason that I ask is that when I use my Anveo SIP account on my Samsung Galaxy SII to make calls, I find that the voice quality & reception is really bad.
Do the SIP phones that you are talking about provide a better quality experience?
I have a corded Yealink SIP T-26P. It works great, but who wants to use a corded phone these days? It's life is spent mostly is a loud telephone ringer, alerting my wife and I to pick up our Galaxy Nexus Android phones running Bria over wifi.
I have seen many times on this forum the comment that wifi VoIP phones are not good. I think what this actually means is the persons wifi network is not good. I have had excellent results using VoIP over smartphone wifi for more than three years. Voice quality is excellent, and on G722 calls is nothing short of amazing.
I don't get dropped packets or any other wifi inadequacies unless I go some distance outside the house. Here a SIP DECT phone would probably have superior range. But it is hard to justify buying a $120 phone just so I can walk down the street making a VoIP call. Under all reasonable circumstances, within the house, reception is very good.
All I did to set up a decent wifi network is install an Engenius EAP350 high-power access point in the ceiling in the middle of the house, and implement QoS on my network, both incoming and outgoing. Problem solved. I will also mention I had a standard-power Engenius EAP9550 at the same location before the introduction of the high power version. It worked almost as well, but that extra power is nice.
So don't be afraid of VoIP over wifi. If you already have a smartphone, install Bria and try it out. If you get dropouts, fix up your wifi network. A quality wireless access point costs the same as a SIP DECT phone, but improves ALL your wireless devices. An average size house without tons of metal in the walls should do fine with a centrally located access MIMO access point, especially with high power.--
